Just another in-bad-taste aside
I used to know an almost-deaf and almost-blind image processing algorithm developer who claimed he was the only person in the world entitled to tell Helen Keller jokes. Actually, the idea of a legally blind image processing programmer is pretty funny, even if it is pretty tragic, too. Louis used to wear a hearing aid and Coke-bottle-bottom glasses that looked like submarine portholes, and he actually had to scrape them up along the monitor to be able to see the imagery he was working on, or the code he was typing.
